To all whom it may concern:

Be it. known that LWILLIAM HQJ NNEY,

'tractors,of which the following is a specification, reference being had to the accom This invention is a pul extracting device for conveying pulps or ot er material under water or other. fluids to one or more discharges with little or no agitation and, while it may be usedin various ways, *it is especially adapted for use in connection with ore concentrators, vanner concentratlng mahlnes, classifiers, settling tanks and 'other mining apparatus. A 'The objectof the invention is to provide a machine of this character which will be sini 1e.and practical in construction and excee ingly e ective in accomplishing itspintended purpose.

'lVith the above and other objects in view, the invention consists of the novel features of construction and the combination and air-*- rangement of. parts hereinafter: fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is'a longitudinal section throu h a pulp concentrator having a central. dis-. charge; Flg. 2 is a vertical transverse'section; Fig. 3 is a top plan view; and Fig. 4 is a longitudinalsection throu h a modified an end discharge is employed; 4

The invention comprises a settling tank or box 1 having one or more downwardly inclined side walls so that the box is of substantially V-shape in cross section'to cause the pulp or solid matter in the water or other liquid discharged into the box to settle upon its bottom. Extending lon itudinally through the reduced bottom 2 0 this pulp settling box is a rotary feed .screw or worm 3 which receives the pulp between its spiral flange or blade and conveys it longitudinally to one or more discharges which may be lo cated at the end or ends of the box, as shown in Fig. 4, or at the center, as shown in Fig. 1. When the center discharge is em loyed the screw 3, which is referably a flat bar or strip of metal twisted into spiral shape has its portions on opposite sides of its center twisted. in o po'site directions, that is, one being twisted to the .right and the other to the left so that the screw will feed the pulp toward the center of the box. The portion of the feed scre'w at the center of the box and opposite a tubular discharge spout 4 extends through a tubular housing which forms a pressurebox 5, and the portion of the screw at the center of said box, vwhich portion is directly opposite the spout 4, is

flat 'or without'a twist so as to forin a rotating paddle 6v which will force the pulp out of the spout 4'.' .The top of the housing or pressure box 5 is preferably, but no nec-' with oppositely .and' downof' the box and to one end of said shaft may be connected any suitabledriving mechanism. As illustrated, oneend of said shaft has fixed to itabeveled gear 9 meshing with a .similar gear 10' on a verticalshaft 11.

This shaft has'its upper end suitably journaledand its lower end mounted in a step and thrustbearing 12. On the upper portion of the shaft 11 is a beveled gear wheel' 13.which engages a gear wheel 14: on a drive shaft: 15.

In order to control the density or thickone of a series] of reducing --tubes 16. These tubes may have openings of different sizes so that "whena tube with a small 0 ening is used the pulp when. discharged rom the spout will be thickerthan it would be if-a' tube having a large opening were used.

In the end discharge pulp extractor shown in Fig. 4, the spout 4 is arranged upon the end wall of the settling box 1 and at the outer end of a pressure box or housing 5 into which the screw .or worm 3* extends.

The use and advantages of the invention will be readily understood from the above description .by any "one skilled in the art.

Itmay be noted, however, that the invention is especially adapted for use in connec-.

tion with vanner concentrating machines and other mining apparatus but it may be eifectively used wherever it is desired to separate pulp or other solid matter from liquid I 110 without a 'tating-the liquid. 7 While have shown and described in detail thepreferred embodiment of the inven ness of the pulp discharged from the spout 4, the latter, is I preferably 'made comparatively large in diameter so as to receive any .ing boxes at the ends of said box, a feed screw arranged longitudinally inthe bottom tion, I wish it understood that I do not limit myself to the precise construction set forth i and that various changes in' the form, proportion and arrangement of parts and in the details of construction may be resorted to Within the spirit and scope of the invention.

Having thus described the invention what is claimed is: i

In an apparatus of the character described, the combination of a settling box having downwardly converging Walls, studof the box and rotatable in said stu'fling boxes, said screw having right andleft hand threaded portions and a fiat intermediate portion, a pressure box or housing arranged in the settling box over said flat intermediate portion of the screw and having its top WILTJLQI ll.
